How do you analyze nominal and ordinal data?
Data Level and Assumptions
In ANOVA, the dependent variable must be a continuous (interval or ratio) level of measurement.
The independent variables in ANOVA must be categorical (nominal or ordinal) variables.
Like the t-test, ANOVA is also a parametric test and has some assumptions..
What is the nominal scale of analysis?
A nominal scale is the 1st level of measurement scale in which the numbers serve as “tags” or “labels” to classify or identify the objects.
A nominal scale usually deals with the non-numeric variables or the numbers that do not have any value.
A nominal scale variable is classified into two or more categories..

What is the statistical test for nominal scale?
Statistical tests for nominal data
Chi-square tests are nonparametric statistical tests for categorical variables.
The goodness of fit chi-square test can be used on a data set with one variable, while the chi-square test of independence is used on a data set with two variables.Aug 7, 2020.

What statistics can be used in nominal scale?
Nominal data analysis is done by grouping input variables into categories and calculating the percentage or mode of the distribution, while ordinal data is analyzed by computing the mode, median, and other positional measures like quartiles, percentiles, etc..
What statistics can be used in nominal scale?
To analyse nominal data, you can organise and visualise your data in tables and charts.
Then, you can gather some descriptive statistics about your data set.
These help you assess the frequency distribution and find the central tendency of your data..
